[Haskell-cafe] Slow IO or bad code?

Your code writes
15 to stdout which is correct (with the example given on the page)..
You have to explain what you mean by >>seems to give "Time limit exceeded"<<

> loop t function
Does already exist.
sequence $ replicate 10 function
is a much shorter way :-)

oor perhaps mapM_ [ function | i <- [1..10] ] )

prod, to_int:
You can both implement using higher order functions

prod = sum . zipWith (*)
to_int = map read
